Before You Start Playing
Turning the FR-4x On
Once everything is properly connected (p. 10), be sure to follow the
procedure below to turn on their power.
If you turn on equipment in the wrong order, you risk causing
malfunction or equipment failure.
1. Turn the [VOLUME] knob all the way to the left to
minimize the volume.
NOTE
5 Before turning the FR-4x on/off, always be sure to turn the
volume down.
5 Even with the volume turned down, you might hear some
sound when switching the FR-4x on/off. However, this is
normal and does not indicate a malfunction.
5 If the message “Battery LOW!!” blinks in the display when
using the unit on battery power, the batteries have run low.
The FR-4x lets you check the remaining battery capacity at
any time (p. 29).
2. Press the [
L
] button.
The power will turn on, an opening message will appear in the
FR-4x’s screen, and then the main page will appear.
After a brief interval, the FR-4x will be ready to produce sound.
3. Use the [VOLUME] knob to adjust the volume.
NOTE
This unit is equipped with a protection circuit. A brief interval
(a few seconds) after turning the unit on is required before it
will operate normally.
4. Adjust the volume of the connected audio
equipment (if connected).
Turning Off the Power
NOTE
Never switch off the FR-4x while playback or recording is
running or while data are being read from, or written to, a
USB flash drive.
1. Turn the [VOLUME] knob all the way to the left to
minimize the volume.
You should also minimize the volume before connecting the FR-4x
to equipment such as an amp.
2. Hold down the [
L
] button until the display
indication disappears.
When you release your finger, the power turns off.
If you don’t want the power to turn off automatically,
turn the “Auto Off” setting off!
With the factory settings, the unit’s power will automatically be
switched off 240 minutes after you stop playing or operating the
unit.
Shortly before the FR-4x shuts down automatically, the display
starts counting down the seconds.
If you want to keep using the FR-4x at this stage, press any
button.
If you don’t want the power to turn off automatically, change the
“Auto Off” setting to “OFF” as described on p. 74.
NOTE
If you need to turn off the power completely, first turn off
the [
L
] switch, then unplug the power cord from the power
outlet.
Refer to “Connecting the AC Adaptor” (p. 10).
Adjusting the Sensitivity of the Bellows
Like acoustic accordions, the FR-4x/FR-4xb produce sound when
you use your left hand to open and close (expand and contract) the
bellows. In general, sound is not produced unless you move the
bellows.
On the FR-4x/FR-4xb, you can adjust the sensitivity of the bellows
to your preference.
To adjust the sensitivity of the bellows, you’ll use the bellows
resistance regulator located at the side of the left-hand bellows
strap, and a setting within the FR-4x (bellows curve).
1. Use the bellows resistance regulator to adjust the
resistance of the bellows to being opened or closed.
Turning the bellows resistance regulator changes the resistance
when opening or closing the bellows.

2. Hold down the [SHIFT] button and press the right-
hand register [7/14] button.
The following screen appears.
3. Use the VALUE [-] [+] buttons to change the value.
For details, refer to “Bel Curv (Bellow Curve Type)” (p. 72).
